- DART CONSTRUCTION Filed July 24, 1956 0220M ,SZL'QFZZ V INVENTOR BY 7A I l ATTORNEYS UnitedStates Patent 1 2,828,966 DART CONSTRUCTION OttoM. Swartz, Chicago, 11!. Application July 24, 1956, Serial No. 599,789 6Claims. (O1. 273-1065) This invention relates to the construction ofdarts designed for use in playing a game wherein a dart is directed at atarget, the dart having a suction cup forming a part thereof which, whendirected against a target will cause the dart to adhere to the targetagainst accidental displacement.

An important object of the invention is to provide a dart which will notonly have exceptional adhesive qualities, but one wherein the vacuumbetween the suction cup and target may be readily dissipated by bendingthe body of the dart above the suction cup laterally, thereby permittingthe quick release of the dart from the target, without damage to thesuction cup or dart proper.

Still another object of the invention is to provide a dart constructionwhich will produce -a more rugged and perfect assembly by the locking inof all integral parts of the dart.

Other and further objects and advantages of the invention will behereinafter described and the novel features thereof defined in theappended claims. I

Referring to the drawing: 7

Fig. 1 is a perspective view of a dart constructed in accordance withthe invention.

Fig. 2 is an enlarged vertical sectional view through the body portionof the dart.

Fig. 3 is a perspective view of the core of the dart around which thedart is built.

Referring to the drawing in detail, the dart comprises a core aroundwhich the body of the dart is formed, the core comprising -a suction cup5 formed with upstanding ribs 6 radiating from the axis thereof, theupper surfaces of the ribs 6 being inclined downwardly towards the axisof the suction cup, as better shown by Fig. 3 of the drawing.

Formed integral with the suction cup 5, is a stem 7 which issubstantially long, and provided at its upper end with a head 8.

The reference character 9 indicates the body of the dart, which isconstructed preferably of sponge rubber.

The body 9 is in the form of a ball with a bore extending therethrough,which bore accommodates the stem 7, as shown by Fig. 2 of the drawing.The lower portion of the bore or body 9 rest directly on the upper edgesof the ribs 6, while the upper portion of the body 9 is flattened toreceive the flat inner surface of the head 8. Thus it will be seen thatdue to this construction the body 9 is firmly held between the ribs 6and head 8, securely locking the body to the core of the dart.

The head 8 is formed with openings 10 that have their walls inclinedtowards the stem 7, the openings 10 being arranged equal distances apartproviding supports for the quill ends 11 of the feathers 12 so that whenthe quills 11 are forced into the openings 10, the ends of the quillswill contact the surface of the stem 7 causing the quill ends of thefeathers to bend slightly as shown by Fig. 2, the rubber of which thebody and head are formed being such that the quills of the feathers willbe firmly gripped and held in position by frictional contact.

From the foregoing it will be seen that due to the construction shownand described, I have provided a dart which is exceptionally rugged towithstand the severe strain to which it may be subjected, and at thesame time provide a perfect assembly by the locking in of all theintegral parts of the dart, without the necessity of the use of adhesivematerial.

. It will further be seen that because of this specific construction asset forth, the dart will be readily released Patented Apr. 1, 1958 fromthe target by merely directing pressure laterally at the upper portionof the body 9 to cause the body 9 to move laterally against the ribs,relieving the point of connection between body 9 and suction cup 5 ofstrain incident to the twisting of the body 9 with respect to thesuction cup 5. By this action the vacuum between the cup and target willbe dissipated since such lateral movement of the body will permit aportion of the cup to become disconnected from the target, allowing airto enter the cup.

While the specific details of one embodiment of this invention have beenherein shown and described, the invention is not confined thereto aschanges and alterations may be made without departing from the spiritand scope thereof as defined in the appended claims.

What is claimed is:

1. In a dart, a core comprising a stem, a head formed integral with oneend of said stem, a suction cup formed integral with the other end ofsaid stem, a sponge rubber body in the form of a ball disposed betweensaid head and suction cup in contact therewith, and feathers extendingfrom said body at the opposite side of the body from said cup.

2. In a dart, a core comprising a stem having a suction cup formed atone end thereof, spaced radiating ribs extending from one surface ofsaid suction cup, a rubber ball-like body secured around said sternresting on said ribs, a head formed on one end of said stem contactingwith said body, securing the body to said stem and feathers secured tosaid body effecting direct line movement of said dart when directedtowards a target.

3. In a dart, a core comprising a stem, a head formed integral at oneend of said stern, a suction cup formed at the other end of said stem, aball-like body constructed of sponge rubber material held between saidhead and suction cup in contact therewith, and feathers extending fromthe body at a point opposite to said suction cup.

4. In a dart, a core comprising a stem, a head formed integral at oneend of said stem, a suction cup formed integral with the other end ofsaid stem, a body in the form of a sponge rubber ball held between saidhead and suction cup, said stem being embedded within said body, andfeathers extending from said body at a point opposite to said suctioncup.

5. In a dart, a core comprising a stem, said stem having a head formedat one end thereof, a suction cup formed at the other end of said stem,a body constructed of sponge rubber formed around said stern betweensaid head and suction cup, ribs extending from said suction cup on whichsaid body rests, providing spaces between said ribs, and featherssecured to said head.

6. In a dart, a core comprising a stem, a suction cup formed integralwith the stem at one end thereof, spaced radiating ribs extending fromone surface of said suction cup, the upper edges of said ribs beingbeveled towards the axis of said suction cup, a rubber ball-like bodysecured around said stern resting on said ribs between said cup and saidhead, securing said body to said core, said head having openings formedtherein, the walls of said openings being inclined towards said stem,and feathers having quills extended into said openings securing saidfeathers to said dart.
